> When writing a pandas dataframe to feather using its to_feather method, 
> sometimes a single column's conversion fails in pandas_compat.convert_column, 
> which leads the whole method to fail. The error message should include the 
> name of the column that failed for easier debugging.
>  
> Eg instead of:
>  
> {code:java}
> ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python 
> object of type int but can only handle these types: str, bytes.
>  
> {code}
> Throw:
> {code:java}
> ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python 
> object of type int but can only handle these types: str, bytes. (column 
> "user_id")
> {code}
